Re: Clipboard access through events

As I've mentioned before, I'd also like to see clipboard access. Obviously,
security is an issue, and I would not object to an explict warning to the
user; I don't think that it would be too onerous to have an initial
permission box pop up, and I'd rather that SVG not get a reputation as a
security risk.

At the same time, however, I do not like the idea of there being fuctions
that are only accessible through the context menu of the viewer; I'd like to
see all these functions exposed through script (ASV3 has several of these:
Open, OpenNew, ZoomIn, ZoomOut, OriginalView, Quality, Pause, Mute, Find,
FindAgain, Copy, CopySVG, ViewSVG, ViewSource, SaveAs, SaveSnapshotAs). Why
not let the user decide what permissions the UA and the authored script
have?

Currently in IE, you (sometimes) have access to the clipboardData object,
but this is very limited. The format of this data is only "text" or "url".
As far as I can tell, neither of these formats is where a raster picture,
for example, is stored when I select "Copy" on  IE's context menu for a
photo. Therefore, I could never paste a photo into an SVG, or copy a
rasterized version of an SVG image into the clipboard, using this method.
I'd like deeper and more consistant cross-platform access.

Getting the result of something like SaveAsRaster, and copying it to the
clipboard would allow us to make applications where we would not have to
"Paste special" in Word or other desktop apps; the user could simply copy
and paste into their favorite raster-friendly app. It would be great to be
able to store multiple formats in the clipboard (an SVG version, a raster
version, and a code-text version of the same SVG image, for example) where
the appropriate one is pasted into the target, but that's getting pretty
picky, and I don't know how well that would take cross-platform.

As Tim said, this is one more thing that would open up SVG to be a true
application framework.

My two cents-
